of series, sequences, integrals
The calculation of, respectively, the sums of series, the limits of sequences, and the values of integrals. The term "summation" also signifies the actual definition of the sum of a series (limit of a sequence, value of an integral), where in the usual definition these values do not exist, i.e. the series (sequence, integral) diverges. Such a definition is usually given in the form of a rule, and is called a summation method of series (sequences, integrals), cf. Summation methods.
